Die Erfindung betrifft eine Einrichtung zum Überführen eines feinzerteilten festen Stoffes, insbesondere eines für die Vergasung mit sauerstoffhaltigen Gasen vorgesehenen Brennstoffes, aus einem Raum von im wesentlichen Normaldruck in einen unter erhöhtem Druck stehenden Raum.The invention relates to a device for transferring a finely divided solid material, in particular a fuel provided for gasification with gases containing oxygen, from a space of essentially Normal pressure in a room under increased pressure.

Eine der Hauptschwierigkeiten beispielsweise bei der Vergasung von Kohlenstaub in der Schwebe mit Sauerstoff oder sauerstoffangereicherter Luft besteht da rin, den Kohlenstaub in das unter erhöhtem Druck, z. B. einem solchen von 30 atü, stehende Vergasungssyetem einzubringen. Zur Lösung dieses Problems sind bereits mehrere Vorschläge gemacht worden. So besteht einer darin, den Kohlenstaub mittels eines Preßstempels in einem kanalartigen Gang zu einem Stopfen zu verdichten, der die Abdichtung der beiden Räume unterschiedlichen Druckes gegeneinander übernehmen soll und der vor Eintritt in den Vergasungsraum wieder fein aufgemahlen und mit dem Vergasungssauerstoff One of the main difficulties, for example, in the gasification of coal dust in suspension with oxygen or oxygen-enriched air is there, the coal dust in the under increased pressure, z. B. to bring such a 30 atü, standing gasification systems. Several proposals have already been made to solve this problem. Thus a is to compact the coal dust by means of a pressing die in a channel-like passage to a plug which is to take over the sealing of the two spaces of different pressure against each other and again finely ground before entry into the gasification chamber and the gasification oxygen

After another suggestion takes place the introduction of coal dust via a multi-stage Sehleussystem. During the first strike, the reliable sealing of the two rooms causes certain difficulties in relation to each other, the second proposal is the pressure losses in the lock system disadvantageous.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung zu schaffen, die einerseits zu ledern.

Time © ine ensures good sealing and the other hand, the removal of print medium from the avoids space located under increased pressure. The pressure medium can be an inert gas, for example -Nitrogen, be with that for security reasons the pressure vessel upstream of the actual gasification chamber is acted upon.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß zwischen den beiden Räumen unterschiedlichen Druckes in einem Gehäuse ein kugelförmiger Körper angeordnet ist, der um eine horizontale Achse drehbar ist und der senkrecht zu dieser Achse eine Seilbohrung aufweist, in der ein Kolben vorgesehen XBt, wobei dieser Kolben in koaxialer StellungTo solve this problem, the invention proposes that different between the two rooms Pressure in a housing a spherical body is arranged around a horizontal Axis is rotatable and which has a cable bore perpendicular to this axis in which a piston is provided XBt, this piston in a coaxial position
